"how to prepare an expository sermon, how to exegete a passage for a college/seminary research paper, and how to prepare a presentation for a Bible study. I imagine you’ll also see some special guests, who will share their unique uses of Accordance."

One important task-based topic would be personal study strategies (involving setting up various workspaces and highlights categories, using auxiliary Accordance modules such as the Timeline & Atlas, etc.), something along the lines of the "Study of Mark" series.

These various topic-based training videos will offer a tremendous supplement to the Accordance introductory tutorials.  Fantastic!  Thanks for devoting all this effort to free online training!
